University project aims to reinvent the wheel

Scientists at the University of Portsmouth in the UK have developed a "smart" wheel that uses artificial intelligence technologies to adjust its behaviour on the road.

The wheel is being developed in a project with Hampshire-based company PML Flightlink.

University scientists are providing the artificial intelligence systems for the wheels on the company's prototype eco-friendly electric super-car. The wheels use microcomputers to perform 4000 calculations per second and "talk" to each other. The wheels use AI to think and learn as the car is being driven, making calculations and adjustments according to travelling speed and road conditions.

The university says this is the first time artificial intelligence has replaced fundamental mechanics within a motor vehicle and will mean tighter control, a smoother ride and a safer drive, yet the driver remains in control of the car.

"Conventional wisdom says you can't reinvent the wheel. We have done just that. We have taken the wheel, given it brains and the ability to think and learn. It's a huge breakthrough," said Dr David Brown of the University's Institute of Industrial Research.

Artificial intelligence controls the suspension, steering and braking systems, teaching it to adapt to bends in the road, potholes and other potential hazards, and compensating by adjusting the car's reactions. The information is retained in the computer's memory and used the next time the car encounters similar road conditions. The car is learning as it drives and adapting its performance accordingly.

Brown said: "Traditional suspension means the vehicle dips when the wheels detect poor road surfaces and you get a bumpy ride, while a tight corner means the drag will slow the vehicle down. Electronic traction control and suspension will counterbalance this kind of drop and drag effect but the driver won't even know it's there. It means a faster car but a safer one."

He added: "The next generation of vehicles have the potential to be fully autonomous, but where's the fun in that? People get pleasure from driving and they will always want the freedom to drive how and where they please."

PML Flightlink designs specialist electronic motors and its electronic vehicle prototype has already received rave reviews at international motoring trade exhibitions.

The company has successfully converted a Mini into an electric vehicle (EV) with four direct-drive wheels, each with an electronic hub motor of 160 break-horse-power. This combined 640 bhp allows for an acceleration of 0-60mph in 4.5 seconds and a top speed of 150 mph (240 kph).
